SPECIFICATION forming part of Letters Patent No. 447,923, dated March10, 1891.

Application filed June 11, 1890. Serial No. 355,022. (No model.)

To all whom, it may concern:

Be itknown that I, \VILLIAM OLARKTHORN- TON, a citizen of the UnitedStates, residing at Jefferson City, in the county of Cole and State ofMissouri, have invented certain new and useful Improvements inMilk-Cans; and I do hereby declare that the following isa full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same.

My invention relates generally to milkcans, and particularly to thatclass thereof known as creaming-cans.

The object of my invention is to provide a can of the characterdescribed that will be cheap and simple in construction and one thatwill hermetically seal the contents when the can is submerged in water,and cool the exterior and interior portion thereof all at one and thesame time.

With this object in View my invention consists of a can having a centralwater tube or channel extending entirely through the same and a coverhaving depending inner and outer flanges adapted to fit over the innerand outer edges, respectively of the central tube and can-body proper,to hermetically seal the contents of the can when the same is submerged.

My invention consists, further, in certain details of construction andcombination of parts such as will be hereinafter described, and pointedout in the claim.

In the accompanying drawings, Figure 1 is a central vertical section ofmy improved can as in use, the central tube being threaded and securedin the threaded collar on the bottom. Fig. 2 is a view similar to Fig.1, but showing the central tube soldered in the bottom, and also thebracing-rods at the top to hold the central water-tube securely inplace.

In carrying out my invention I employ a can A of any suitabledimensions, and in the bottom a of said can is formed an aperture,preferably circular in shape, and within said apertured bottom issecured the watertube B, said tube extending from the bottom a entirelythrough the can to a point slightly above the upper edges of. the can,as clearly shown. The central tube may be secured in the bottom bythreading the same, as shown is turned, is sufficient toretain said tubein a verticalposition but when said tube-is soldered in the bottom it ispreferred to brace the-same at its upper end by means of the radialbrace-rods 0, extending from the top of the tube to the upper edges ofthe milk-can. A ring G, having arms G, is preferably employed to holdthe upper portion of the tube in position. Said ring is slipped over thesaid upper end of the tube, and the arms G have bifurcated ends whichremovably bear on the top edge of the can-body A. By this means ofconstruction and arrangement the parts are strengthened and made readilydetachable and removable.

The top 0 of my improved milk-can consists, as usual, of the top portion0 and the depending flange or rim 0 but at its central portion is formedan aperture d, in which is secured the depending'tube or collar D, saidcollar being so arranged and constructed that when the cover is properlyplaced upon the can the depending collar D will enter the central tubeB, thus securely closing the can and forming a tubular passage orchannel entirely through the same. The object of the central tube is toexpose the central portions of the milk to the cooling influences ofwhatever medium may be employed to cool the outer portions thereof.

While my can could be used in the air, it is preferred to place the samein a tank of cool water, the water being of such depth that the waterwill rise in the central tube when the can is submerged. The water,entering the central tube, quickly cools the central portions of themilk. When the cover 0 is placed upon the can, the moment the flange 0reaches the water it hermetically seals the can at its outer edges, andthe lower edges of the collar D coming in contact with the water in thecentral tube seals the inner edges in a similar manner.

From the drawings it will be seen that the cover slopes from the centertoward the outer edges of the can, and the flange c and collar D arearranged at acute angles to said cover.

H indicates handles arranged upon the sides of the can and so placedthat the flange 0 will rest upon the same and support the cover asuitable distance above the can proper. In this Way an air-space isformed, whereby the vapors arising from the milk will be, condensed onthe under side of the cover and conducted down the sloping cover andflange and into the submerging liquid.

I indicates a faucet tapped midway the height of the can, and Iindicates a creamgage constructed and applied in the usual manner.

To rend er the can suflioiently heavy to sink, I employ a flat metallicring K, attached to the bottom, and, if desired, the bottom may bedouble and the ring secured between the two bottoms. Below said ring andthe lower bottom and in the extended sides of the can are formed aseries of perforations 7a to permit'the escape of air.

Having thus described my invention, what I claim is- In a milk-can, thecombination, with the can-body, of the double-Weighted bottom having acentral screw-threaded opening, a central tube having its lower endseated in said screw-threaded opening, a ring removably IV ILLIAM CLARKTHORNTON.
